Abstract

Aryl-and silyl-terminated 6, 7-dialkynylpyrazino [2, 3-f][1, 10] phenanthrolines (pyzphen) have been prepared by the condensation of [1, 10] phenanthroline-5, 6-diamine with appropriately functionalised dialkynyl-1, 2-diones. These new ligands were used as chelators in the formation of the corresponding [Ru (bpy) 2 (pyzphen)]· 2PF6 and [Ru (phen) 2 (pyzphen)]· 2PF6 complexes. The terminally free diethynyl [Ru (bpy) 2 (pyzphen)] ...
